Active Surfactant Matter (ASM) Calculator - Digital Download
If you make body wash, shower gel, hand wash, shampoo or any foaming or cleansing product, it's important to calculate active surfactant matter (ASM).
Doing this requires a bit of maths and a fair bit of tweaking to get your products ASM in a suitable range.

- Information on how to calculate ASM manually.
- Cheat sheet for the recommended ASM level for different product types.
- Pairings for compatible charges.
- Pairing suggestions for surfactants for different product types.
- Full calculator with ready-made list of surfactants, their charges, ASM and pH
- Space to add your own
